METHODS AND APPARATUSES FOR DYNAMIC ANTENNA ARRAY RECONFIGURATION AND SIGNALING IN MILLIMETER WAVE BANDS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240349073 titled 'METHODS AND APPARATUSES FOR DYNAMIC ANTENNA ARRAY RECONFIGURATION AND SIGNALING IN MILLIMETER WAVE BANDS

The present disclosure pertains to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) can detect an antenna array change condition and transmit a request for beam training for an antenna array configuration in response to the detection. The request for beam training includes a requested antenna array configuration for the UE and an indication of beam weights to use with the requested configuration. A base station determines whether to grant or deny the requested antenna array configuration for the UE. The UE receives an indication of an antenna array configuration from the base station and trains the reconfigured active antenna array configuration based on reference signals.

• User equipment (UE) can detect antenna array change conditions.
• UE transmits a request for beam training for an antenna array configuration.
• Request includes requested antenna array configuration and beam weights.
• Base station decides to grant or deny the requested configuration.
• UE trains reconfigured active antenna array based on reference signals.

Potential Applications: - 5G networks - Wireless communication systems - Beamforming technology

Problems Solved: - Efficient antenna array reconfiguration - Improved signal transmission in millimeter wave bands

Benefits: - Enhanced network performance - Increased data transmission speeds - Better signal reliability

Commercial Applications: Title: Dynamic Antenna Array Reconfiguration for 5G Networks This technology can be utilized in telecommunications companies to enhance network performance and data transmission speeds in 5G networks, improving overall user experience and connectivity. The market implications include increased demand for advanced antenna array systems in the telecommunications industry.

Questions about Dynamic Antenna Array Reconfiguration: 1. How does dynamic antenna array reconfiguration improve signal transmission in millimeter wave bands? Dynamic antenna array reconfiguration optimizes signal transmission by adjusting the antenna configuration based on changing conditions, leading to improved network performance and reliability. 2. What role does beam training play in the reconfiguration process? Beam training helps the user equipment (UE) adapt to the new antenna array configuration by adjusting beam weights, ensuring efficient signal transmission and reception.

Original Abstract Submitted

the present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. a user equipment (ue) may detect an antenna array change condition. the ue may transmit a request for beam training for an antenna array configuration in response to the detecting. the request for beam training may include a requested antenna array configuration for the ue and an indication of beam weights to use with the requested antenna array configuration. a base station may determine whether to grant or deny the requested antenna array configuration for the ue. the ue may receive, from the base station, an indication of an antenna array configuration for the ue. the base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (csi-rs). the ue may train the reconfigured active antenna array configuration based on the reference signals.
